Battery Backup - System Memory
Description
The battery on the CPU retains the Clock/Calendar when the CPU encounters a power loss. With a
fully charged battery, the settings are retained for approximately three years.
The system programmed memory (Customer Database) is stored in Nonvolatile Memory and can be
erased only by performing a First Initialization.
For additional storage time and the database and Caller-ID History can be copied to the system drive on
the CPU-C1.

(protection against loss of power) just before ETU installation to provide battery backup for System
Memory.
• When fully charged, the battery retains System Memory for approximately three years.
• You should replace the CPU-C1 battery every three years.
